Learned something new - I though I've read a post from someone that they were mandatory but I think I have mixed that up with front driving lights - those are mandatory, right? Getting old...LOL
Sorry, my mistake then...
I think what I should have said that many cars imported into Canada come with pre-wired rear fog lights...is that the case Plain OM?
Actually, I think what you meant is Daytime Running Lights...and you're correct Jogo, those are mandatory in Canada
Many, but not all, modern vehicles that have a rear fog light option in non-North American countries are pre-wired for the option. I believe this is because it's less expensive to create one master wiring harness for the world, then just plug in the needed items for each of the respective markets. Pretty much any modern BMW or Audi has this pre-wiring and only requires the European headlight switch to become operational. I've owned a couple of VW's (99 and later) where the Euro switch and one wire were all that was needed to get rear fogs working.
I've also lived in states which require annual or initial vehicle inspections. In those locations, based on my personal experience, the inspectors check to ensure that you have
all of the required safety equipment, but they do not penalize you for additional items
(fog lights, driving lights, horn, etc) provided the stock, required items are present
. In some states, even emission controls are checked to ensure they are present. I speak with confidence when I say that adding a rear fog light, stock or aftermarket, will not invalidate an inspection so long as it has an on/off switch. The exception would be for accessory items which are poorly installed and/or cause a legitimate safety hazzard to other motorists.
While a law enforcement officer might stop a car with an operating rear fog lamp, possibly thinking it's a brake lamp and the other side is burnt out, a quick explaination will get you back on the road without a ticket. If you have a suspended license, or warrants for your arrest, you may not want to use a rear fog lamp, to minimize your potential contact with the po-po. Again, based on my experience, folks with those conditions display plenty of other reasons for a traffic stop and likely don't know what a rear fog lamp is
